Mehtre, Associate Professor, IDRBT, Road No.1, Castle Hills, Masab Tank, Hyderabad 500057, (Mehtre@idrbt.ac.in ) Abstract: Denial of Service (DoS) is a major threat in every type of Computer Network, including Internet, Cloud Services and Sensor Networks. In this paper we propose novel Security Metrics to compute the severity and impact of a Denial of Service (DoS) attack, which helps to accurately and precisely estimate the monetary loss incurred by an organization. These metrics are quantitative in nature and map Quality of Service (QoS) requirements into measurable and acceptable threshold parameters. The test results of the application of these metrics using Network Simulator are presented. The work for implementation of these metrics in Network Management Systems (NMS) and Visualization tools is in progress. Key Words: Security Metrics, Denial of Service, Network Attack 1. INTRODUCTION Metrics are scales of measurement used for improvement and scientific decision making. Security metrics are useful for quantitatively measuring an organization’s security level or of security vulnerabilities of an entity. For comprehensive network security and Cyber Situational Awareness Management, security metrics play significant role as proactive protection measures rather than reactive analysis
